    I had figured out how to mount the C7 tail lights and Kevin had sorted out how to fit them into the body. So it’s time to just do it, right? Nope… Brian mentioned the 2020-2021 Toyota Supra tail lights which weren’t out when I settled on the C7 lights. They are more modern, exotic and make the...

    Good source for carbon fiber / epoxy supplies?

    Only buy brand-name epoxy resin. There's a handful to choose from, but I've had good experience with West Systems and Total Boat. Alan, who has built 20+ SLCs uses Total Boat. Both he and I are located in the North East so we buy our composite supplies from Jamestown Distributors because they...

    Abe's a pro so he was able to achieve the results without any special equipment. Edges were deburred, a tube polisher with a surface conditioning belt was used to clean clean the surface, acetone was used to degrease, clean gloves were used, pure argon with a healthy flow was used to back purge...

    Titanium pie cuts before deburring and surface conditioning and 3D-printed tube clamp I’m going to run an x-pipe under the transaxle. Since I’m primarily interested in smoothing and reducing the magnitude of the exhaust, as opposed to maximizing HP, I went for what would fit best. The x-pipe is...

    Mason, it's a lot of work just to mock things. The biggest challenge now is to figure out how to temporarily stiffen the tail so that I can start testing some air springs. ============= LS engine oil inlet fittings; Daily Engineering (left) and Kurt Urbane (right) In a previous post I...

    Slc rear wing uprights

    Note that Superlight offers a wing option for the race tail, but not for the street tail. If you want a street tail, AFAK you'll need to fabricate your own support.

    Neil, I'll have the engine tuner ask him when I get to that point... he clearly doesn't want to see cats on the engine LOL As I’ve previously mentioned, I’m completely changing the rear 20% of the tail. The stock tail is a single pivoting piece that supports the tail lights and has an...

    I started fabricating the cat-back exhaust system. The plan is to fabricate stainless steel sections for the catalytic converters (cats) that connect to the merge collectors and titanium mufflers via v-bands. My engine builder recommended an Air-Fuel Ratio (AFR) of 10.5-11 which is crazy rich...

    Good catch Neil... they're about 3.5"

    Rich, Thanks for the compliment. The rear springs are Eibach 0600.250.0750 (link here EIBACH COILOVER SPRING). They are 750 lbs/in and have an OD of about 1.6" which provides plenty of clearance.

    I mounted the rear sway bar in a previous post and the next step was to attach it to the bellcranks. The adjustable sway bar blade accepts a 3/8” rod end. However, the other side of rear sway bar link is attached to the same 1/2” bolt that affixes the shock absorber to the bellcrank. While it...

    I finally got around to installing the triple-carbon clutch that I discussed in a previous post. The first step was to install the pilot bearing in the crankshaft. I applied a little anti-seize on the sides and used a 32 mm socket, a short socket extension and a hammer to tap it into the...

    Jeff, I didn't find a solution that I liked. I considered fabricating a manifold, but here's why I went with separate hoses: It's easier to route two smaller hoses than one large one Swivel fittings make it easy to tweak orientation (i.e., things change!) I was able to use Wiggins clam-shell...

    Build/Assembly manual

    Raul, The spider is going to come on and off a lot. I've taken it off and then put it right back on to figure how much clearance I had for whatever I was going to do. The way to reduce that is to use a Sharpie to mark the chassis, take some measurements and take a bunch of pictures. Another...

    Front wheel speed sensor location

    I'm not familiar with the Graziano, but I don't see how the front wheel shaft helps you with "engine speed". I assume that you're referring to RPM and to get that you would need to know what gear you're in so that you could take into account the effective gear ratio (i.e., actual gear * drop...

    I installed the flywheel today. I have an LS7 so I ordered an LS flywheel locating dowel and when I went to install it I realized that it was way too small. WTF? I have a built motor and it has a Callies DragonSlayer billet crankshaft with an LT, rather than an LS, bolt pattern. D’OH...

    I should have mentioned that if the parts meet a certain size criteria they deburr both sides which usually removes all of the mill scale. Below is a picture of my first order. It's mostly 1/8" 4130 with a few piece of 1/4" 6061. Most of the pieces were deburred. The orders are shrink wrapped...

    Alan, I highly recommend SendCutSend.com. They have outstanding prices, online quoting/ordering, lots of of material choice, typically a one-week turn around. Their quantity one pricing is lower than my local company's quantity 50 pricing and they're 2-3x faster because the local guys aren't...

    The Albins ST6-M automatically locks the reverse gear out. To put it into reverse the driver must pull a cable to disengage the lock and only then downshift. This makes a lot of sense because it’s a sequential transaxle and you don’t want the driver to accidently put the car into reverse when...
